Abstract

The invention discloses an RTM (resin transfer molding) technology for composite material molding. The RTM technology for composite material molding comprises the following steps of: step one, placing glass fiber reinforcing materials in advance in a mold cavity of a mold; step 2, injecting a prepared resin glue solution into the mold cavity from an injection hole after a mold is closed and locked at certain temperature and pressure, and soaking the glass fiber reinforcing materials; and step 3, controlling the temperature and curing through a heating device in the mold, starting up the mold, and demolding. The RTM technology for composite material molding disclosed by the invention can effectively solve the problems of longer molding time as well as great product deformation in the prior art, and the technology is low in production cost, and is beneficial to popularization.

Description

technical field [0001] The invention relates to an RTM forming process of composite materials, in particular providing a process in which a heating device for maintaining a specific temperature is arranged in a forming mold, and a temperature control technology is used to control the curing of composite material products. Background technique [0002] RTM (Resin Transfer Molding) is the abbreviation of resin transfer molding. It originated from the cold mold casting process in the 1950s and has a history of more than 40 years, but the RTM process has really been valued by people and has developed rapidly only in the past ten years. Because this process has a series of advantages such as high efficiency, low investment, good working environment, low energy consumption, and strong process adaptability, it is very popular and develops rapidly. Has been widely used in construction, transportation, telecommunications, health, aerospace and other fields. The Japan Reinforced Pla...
